I'm curious if using an extractor hood makes a difference. If it's sized correctly the extractor should replace the air 8-10 times per hour so that should eliminate I guess most pollutants in the kitchen.
Another way to look at the this is checking the health outcomes of chefs, given they spend much more time next to the stove we should see increased respiratory problems.
